BRICK-DRIER.

Application filed September To all who) it may concern:

Be itknown that Llfinwaun H. (Jana-mun, modified manner with a View to making it a citizen of the United States of America,

residing at 'estticld. in the county of Union 3 and State of Xew Jersey, have invented certain new and useful Improvement-s in Brick- Driers, of" which the following is a specification, reference being had therein-to the accompanying drawing.

My presentinvention relates to an apparatus for drying brick and other similar articles.

More particularly it refers to a bricledrying apparatus in which the drying is accomplished by means of a rack of steam heating pipes, or by means of the waste heat supplied from the kiln, or both.

The object is to provide an improved and simplified apparatus whereby the waste heat from the kiln may be utilized in drying the bricks, and whereby an alternative. system may be provided. using at one time the waste heat from the kiln, and at another time the steam heat from the drying racks, whichever may he found preferable.

The invention, therefore, consists essentially in the construction, combination and arrangement of parts, substantially as will be hereinafter described and claimed.

In the accompanying drawing, illustrating my invention, Figure 1 is a front elevation of my improved hrick drier. the ducts for conveying the waste heat and certain other parts being shown in section. Fig. 2 is a top plan view of one of the plates covering the the same. Fig. 4-

section of the drying shed constructed in a entirely fire-proof. Fig. 1]. is a detail partial longitudinal section of the roof of the shed on the line we of Fig. 10, and shows i the arrangement of the air valves.

Similar characters of reference designate. corresponding parts throughout the :litt'erent figures of the drawing.

1 designates the briclcdrying shed which may be of any suitable shape and design and on which I. lay no separate claim at this time. Obviously it may vary in shape and size within very wide limits. \Vithin the shed 1 are the pipe racks of which there may he any number arranged in any desired manner, and operating in the customary fashion for racks of this type. for the purpose of drying the bricks which are placed thereon. in the example of my invention, illustrated in the drawings, it will be seen that each half of the shed 1 contains two rows of brick-drying racks 2. Between the two racks 2 on each side of the shed. there,

may he a conveyor T. as indicated in Fig. 1. for carrying the bricks into the drier. The particular kind of pipe rack may tary greatly, and I do not wish to be restricted to any special kind. I may use the form dcscrihed and claimed in my eel-pending application for Letters Patent on brick drying rack. lilcd March 20. 1908, Serial No. 422.355. or that described and claimed in my other co-pending application for Lettcrs Patent on brick drier. filed March 25, waste heat tunnel. Fig. 3 is an edge \'l(:\\' of 190?. Serial No. 361,503, or that shown in my ulllQl eo-pending application for Letters any other style of pipe rack that may serve the purpose.

partly in section of my improved lu'icl; drier, and indicates the inclined nature of thel ticnlarly the hinge employed to fast n t0 gvtlier th leaves rt whn-h the said partition 1. uuniifllud. 1' in. it) ia l!:||\-\'i;r.--: .t-i'lllfill 'l'iamelt 2 are capableofbcingelleciually inclosed so that the air therein may be heated to the proper temperature to dry the lHl lifi on the lu'iclc-dryiiug' supports. The

; means for llltlflrlllg the racks consists esscnlially of a hinged top cover 27 in the form shown in Fig. 1, and also or a sectional partition or ide cover shown In Fig. 1, and

; in delail in Figs. (3. T. S and 9, said side partition being composed of the leaves 8, 8 and t rcpt-want additional details. more par- 1" and 2 which are. hinged together by i means of hinges J. Thi v partition is hinged Cat instance, the beam 10 (see Fig. 1). The 1 volume of the air will decreasolikewise, and

sectional partition may, theretore, be al lowed to drop down alongside of the rack 2 in the position shown in Fig. (3, where all the leaves oecup a vertical position; or it may be folded up into the position shown in Fig. l, and hung by means of a hook 11; or it may be partly folded, as also indicated at the right-hand rack in Fig. 1, it thus being possible to entirel shut in the rack 2 or to partially inclose it. The sectional cover or partition therefore enables the rack to be inelosed as much as may be necessary to create therein the proper degree of heat for drying the brick.

opened and closed as I have explained, the racks are inelosed on all the other sides, while at the top there is the movable cover 21' already mentioned.

Directly beneath the pipe racks 2 are arranged longitudinal ducts or tunnels3 which receive the waste heat from the kiln. These tunnels are shown in cross section in Fi 1, where they are seen to be below the level of i the earth, but. with their top side preferably in the same plane as the surface of the gL'OUIId. Said tunnels are of an desirable length, and shown in Fig. 4 they connect with a common trunk tunnel at, in conjunctionwith which arranged a tan or blower 5 by means of which the waste heat from the kiln is forced through the tunnels or ducts. In the present example of my invention,

Obviously in addi-- tron to the sectional cover capable of being inasmuch as there are two rows of racks in each half of the shed, it is convenient to have parallel tunnels 3. 3 in each half of the shed immediately under the two rows of pipe racks. as clearly indicated in l and I. and under these cireutnstahces these pairs of tunnels 3, 3 have their members uniting with each other at the ends by union pipes 3, said unions 3} entering the main trunk -l as already mentioned. At the junction of the union pipes 23- with the tnztin trunk tunnel 4, l locate a valve (t of any stutable construction having an external handle may be turned into one or the other of the brarch ducts 3 and thus directed to one side or the other of the drying apparatus, or if desired. b placing the valve midway, the waste heat may be allowed to pass to both sides of the drier. In other words 1 cmplo at the junction of the main trunk tunnel with the branch tunnel some sort ol an etl'ert ive valve device 6 for controlling the passage of the heat and for shutting it ett' when desired.

The du ts or tunnels 3 are so'ctntstructcd preferabiv that they gradually narrow in size as they run from the lower toward the far end of the drier, indicated in dotted lines in Fig. so that as the intensity of the pressure and the heat tend to decrease the hence the heating eil'eet will he kept up sub stantially the same throughout the entire length of the ducts. These ducts or tunnels are covered with plates 13 placed thereon tlush, or, at least, preferably flush, with the ground surface, or the surface of the floor of the drying structure. llates 13 are provided with a suitable number of slots or openings ll through which the hot air passes into the space where the bricks or other articles to be dried are located. The slots or opt-nines ll may he of any desired size. These plates lie on the top of the ducts. end to end with each other, and are easily rctnotablc and replaceable when desired.

It. is obvious that the essential principle of my invention consists in employing the waste heat from the kiln for drying bricks in the drier, and in so arranging the construction of the drier that when this waste heat is not available to use for drying the steam heat may be derived from the heating racks in the customary way, and the procedure of drying the brick citrtied on by means of said steam heat. But,of course, for purposes of cheapuess and economy, it is highly desirable to utilize the waste heat from the kiln, and so I have arranged to direct it into the dt'yin; apparatus in an effective and easy manner. Thus the apparatus is an alternative one. capable of dryv iag the brick by means of the heat from the kiln at one time, and adapted at another time to dr) the brick by means otthe heatfrom the drying rack. the result in either case being equally competent.

In Figs. 10 and ll 1 have retnesented a modification in the construction of the shed and in the means for regulating and controlling the air draft through the same and especially through the pipe racks. In this modified onstruction. one of my leading objects is to render the building tire-proof, and t this end the root i is made of concrete of some considerable thickness. as indicated in 1-2, and by means of said valve the hot air 1 Figs. 10 and ll. said concrete material beme prepared and -applted in any. desired manner. Of course when the roof is thus constructed. it is not filllj' tire-proof but is strong and durable. llooi 20' is provided with longitudinal cttpolzts 21 of greater or less size. These are open to the atmosphere on thesides at 2:3. and are provided interiorl v with valves 23 which control the draft between the atm sphere and the interior of the drying: rack, and consctptently between the a mosphere and the waste heat ducts 3. Th said valv s .23 are hung on operating rods 34 which run longitudinally through the cupolas .2. and are provided at :t desired point with an operating: hand-wheel, or some. other suitable coutrivauce, for the purpose of easily manipulating them. in order to conveniently apply and arrange the operating rod 24, the cupola devices 21 are broken at certain points; or, in other words 1 are made in short lengths, as indicated in r Fig. 11, and the. ends of the rod Qlallowrd i to meet between the cupola sections and to be tied together by suitable unions. as at 2:, 1 this construction being simply to enable the parts to be put toget her the more easily ad operated with greater facility. Fnrthcrmore. the fire-proof roof 20 is provided with suitable sky-lights it; which may be of any i desired size and pattern.

Many modifications in the exact construction and arrangement of the various parts i may be made without exceeding the scope of the claims.

Having thus described my invention. what I claim as new and desire to secure by Let-- ters Patent is:
